Default First track days

I'm registered for my first track weekend at Porsche St. Louis High Performance Driver Education event at Gateway, first weekend of April. Was happy to confirm that my convertible has acceptable factory rollover protection and won't need to add anything. Still need a race seat, not for safety, but for head/helmet clearance.

Interesting, NCCC does not allow convertibles without rollbars for high speed events.

I'm a bit confused. What factory roll over protection does c7 convertibles have? Do the C7's now have pop-up hoops to project the occupants in the event of a roll-over?

I don't know either. I got in touch with the guy that runs the club and he said that my car is good to go as is. That's all I need to know

Okay, well post pics when you get the seat & belts installed. I'm interested to see how this will turn out as I've never seen and corvette convertible on the track before. I was under the impression that without major modifications they are not allowed due to safety concerns. Lastly I'm not sure if this applies to your event but the events I run require both seats to be equivalent meaning you'll have to install a seat and harness in the passenger side as well.

Ron Fellows ZR1 owners school at Spring Mtn Jan 25 &26. I just had the pics emailed to me today and noticed that in corner 9 I have pulled the left front off the pavement. Sunlight under it. The cars grip level absolutely amazed me. If you havenít signed up yet, please do. You wonít regret it. Find out where the cars limits are safely.

That's a great pic but, the tire isn't off the pavement. The break in the shadow is the light going between the trailing edge of the splitter and the front of the tire, shining down. The shadow of the tire, attached to the ground can be seen as sun goes beneath the forward outer edge of the tire. The ZR1 won't lift a tire, there is plenty of chassis compliance and droop. When you see cars lifting front tire, it's a combination of a lot of roll stiffness and a twisting chassis...i.e. usually on older race cars. ZR1's aren't lifting inside tires, nor would you want it to.

Until I got pictures from an event at VIR I never felt the right side leaving the pavement. In my C5 both inside tires were lifting from the pavement completely at the top of the uphill esses at something a little less than 120mph. This, without a cage but still a pretty good oem rigid frame. As I said, never noticed it so I suppose the R6's on the left side were holding fairly well.

Well they can lift all four wheels off the ground

I think you better plan on taking another car or making some changes to your car. Here are the PCA Rules for the event you are attending as listed on the Motorsportreg.com website:

Open Cars: Any make of car delivered with factory installed roll over protection meets the minimum standards for Porsche Club of America Driver Education events. In these cars the soft-top must be in the up position or the hard top installed. If the top is in the down position, an SFI and/or FIA approved arm restraint system* must be used. If a car DOES NOT have factory installed roll over protection, a roll bar or roll cage must be installed, which meets the "broomstick" rule (the driver's helmeted head is below a bar placed on top of the roll bar and windshield). Design, installation and materials of roll bars or cages and their installation must meet PCA Club Racing specifications, contained in Appendix A-Roll Cage Specifications of the PCA Club Racing Rules.

The person you talked to must not have realized you are not bringing a coupe. Even if they did let you participate you more than likely wouldn't get any instructors that will ride with you.

OP I also agree you better have a good Plan B. I don't think they will let you track your Z as it sits now. Whatever you were told must have just been a mistake. I go to many of these events and that's safety rule #1 for Vert's. I've never seen them deviate from that at all.

Laps Inc let me track my C6 Callaway Grand Sport Vert a few years back at RA (to my surprise). No roll protection of any kind. Now I notice on Road Americaís site for their own sponsored HPDE days, roll cages are required in drop tops. I think there may be different rules by different event sponsors. I must admit I felt a little foolish going a buck and a half with nothing but an umbrella over my head.
